[QUOTE="bigngreen, post: 384887, member: 13632"] Some think that the chamber pressure will rise due to water taking up area I don't think that is what I have seen. What I have seen is the same chamber pressure but the case is reacting to that pressure differently and I wouldn't think that would show up in bullet velocity. Pressure I don't think increases in the chamber but the pressure is only taken by the surface area of the bolt face with no help from the case wall. Sorry if my point is confusing just not as good with the put together of the word! I would agree with anything being in the bore will cause pressure, been there. If loads were developed with a dry chamber and you change the state of the chamber surface there will be a change in the relationship between the case wall and the chamber, won't there, won't that allow the brass to move back at a more accellerated rate due to lack of resistance of the case wall? One may need a strain gauge that would measure the force applied to the bolt face and chamber. I make a living fixing what engineers screwwed up! [/QUOTE]
